What is the difference between these two LSX blocks, part #s 19213964 and
19166454? I'm wanting to build a motor for 69 Camaro project car or install the new LSX454. Thanks for any help.

This should tell you what you need to know about the differences in blocks. https://ls1tech.com/forums/generatio...ocks-sdpc.html

If I could afford an aftermarket block, I would look into this.....

Thanks for the info. I think I came up with the answer. The 19213964 is the standard block, and the 19166454 is the tall block which is said to handle 2500 HP. That should do the trick.

Actually both of those parts numbers are the standard deck height. The #964 number is the revised part number block and the #454 is the first version block. There may be some of the earlier block still floating around out there but I think there are some improvements on the newer style that are covered in the SDPC link.
